NOAA-GFDL/FMS: 2021.02

[2021.02] - 2021-05-20 Added

• FMS2_IO: Added fms2_io support for boundary condition restarts. register_restart_region_2d and register_restart_region_3d were added to fms2_io's register_restart_field interface and read_restart_bc and write_restart_bc subroutines were added to read and write boundary conditions restarts. See test_fms/fms2_io/test_bc_restart.F90 for sample usage.
• FMS2_IO: Added fms2_io's version of set_filename_appendix. The string sent in will be appended to the filename of a restart/history file before the .nc or before .tile if tile is in the filename.
• FMS2_IO: Added workarounds to get fms2_io code working with pgi
• COUPLER_TYPES: Added fms2_io's version of register_restarts_2/3d and CT_restore_state_2/3d to the coupler_type_register_restarts and coupler_type_restore_state interfaces in coupler_types. The fms_io's versions were renamed as mppio and both versions may still be used. See [test_fms/coupler/testcouplerd.F90](https://github.com/NOAA-GFDL/FMS/tree/9d55115a331685e4c6e01f2dfb3b770a9f80fa37/test_fms/coupler) for sample usage.
• MPP_DOMAINS: Added a subroutine mpp_create_super_grid_domain, which sets the indices of the input domain to match the supergrid domain.
• MOSAIC2/GRID2: Added a version of grid.F90 that is suitable for use with fms2_io called grid2.F90, and moved it into the mosaic2 folder along with mosaic2.F90
• FMS_MOD: Added grid_init and grid_end calls for use with grid2.F90
• TIME_MANAGER: New set_date_gregorian and get_date_gregorian function/subroutine that do not use coded_date and date_to_day arrays are added and set as default. The original get_date_gregorian and set_date_gregorian have been renamed to get_date_gregorian_old and set_date_gregorian_old and can be used by adding old_method=.true. optional argument to set_date and get_date subroutine calls. This is the first step out of three to remove the memory-consuming coded_date and date_to_day arrays from the time_manager_mod.
• FMS GLOBAL MODULE: Adds a new module (libFMS.F90) to be used as a global import for all supported routines/types/variables within FMS. Also adds a separate module (fmsconstants.F90) to be used for constant values from constants_mod. ### Changed
• FMS2_IO: Adds logic so that the domain decomposition variable attribute is only added if the io_layout is not 1,1.
• FMS_IO: Moved get_great_circle_algorithm from fms_io to grid2.F90
• FMS_IO: Moved routines and submodules that were not IO related to fms_mod ###Removed
• DIAG_MANAGER: Removed the variable attributes _FillValue and missing_value from the time_bounds variable to be cf compliant
• FV3GFS: Removes the unused fv3gfs directory
• MOSAIC/GRID: Removed references in grid.F90 to fms_mod(replaced with mpp_mod direct calls)
• MOSAIC/GRID: Moved mosaic/mosaic2.F90 to mosaic2 folder ###Fixed
• DIAG_MANAGER: Fixed a bug where the variable type of Time and Time_bounds were different (float vs double) when compiling with 32 bit reals
• FMS2_IO: Fixed a bug where the code was crashing when you were trying to read/write scalar variables with the domain decomposed fileobj ### Tag Commit Hashes
